Guidance for Conducting Effective Work Zone Process Reviews

All state highway agencies receiving Federal-aid funds are required to perform work zone process reviews every two years. These reviews are an opportunity for the agency to reexamine how it is meeting federal requirements in 23 CFR 630 Subparts J and K in accomplishing work zone safety and mobility management. These reviews help an agency evaluate its work zone safety and mobility-related policies and procedures as well as the effectiveness of its work zone impacts analyses and monitoring efforts, and ultimately, how well it manages those impacts.

The intent of the document is to share good practices and methods that agencies have found worthwhile in conducting their process reviews. The goal is that this focused information will lead to more consistent and targeted improvements in agency work zone policies and procedures. This document includes tips for success in work zone process reviews, effective use of data and performance measures in process reviews, and insight for connecting process reviews with other work zone safety and mobility improvement efforts.
